HAT-rin.

To all whom t may concern:

Be it known that I, WILLIAM A. HARTLINE, a citizen of the United States, residing at Penns Grove, in the county of Salem and State of New Jersey, have invented certain new and useful Improvements in Hat-Pins, of which the following is a specification.

rI`his invention relates to hat pins, and more particularly toa hat pin provided with means for securing the same in a hat.

One of the main objects of the invention is to provide a hat pin of simple construction and operation having means for preventing accidental withdrawal of the same Vfrom a hat. A further'object is to provide a hat pin of the character stated of simple construction and neat appearance which may be produced at relatively small cost. A

still further object is to provide a device for securing a hat pin in a hat which may be readily applied to hat pins of standard construction. Further objects will appear from the detailed description.

Inthe drawings Y j v Figure 1 is a side view of a hat pin having a securing means constructed in accordance with my invention applied, the secur- -ing means being shown in section and in inoperative or retracted position,

Fig. 2 is a similar view showing the securing device in extended or operative position, Fig, 3 is a section on line 3 3 of Fig. 1, Fig. 4 is a section on line 4 4 of Fig. l, Fig. 5 is a perspective detail of the locking spring and the rod carrying the same, Fig. 6 is a view similar to Fig. 2 of a modified form, v Y Y Fig. 7 is a detail central sectional AView through the form of locking device shown in Fig. 6, and

F ig. 8 is a fragmentary detail'showing the locking device as used.

Referring more particularly to Figs. 1 to 5 inclusive-the hat pin A is provided with a suitable head 1 and shank 2 having the point 3 for insertion through the crown of a hat. Shank 2 is provided, in its upper end portion, with an axially extending bore 4, the upper end portion of the shank being interiorly threaded to receive the threaded stud 5 of head 1, the head and shank thus being detachably secured together. A rod 6 is slidably mounted in bore 4, this rod being of such diameter as to tit snugly within the bore, but being of considerably less length than the bore so as to be freely slid- Specication of Letters Patent.

able axially of the same in either direction. A spring steel locking wire spring 7 is carried by rod 6 and is so shaped as to be normally pressed outwardly radially of the rod so as to project through the slot 8 communi.- eating with bore 4 when the spring is moved into register with this slot, as in Fig. 2 of the drawings. The outer end portion of spring 7 is bent to provide an inwardly directed arm 9 disposed at a right angle to the body of the spring, and an outwardly directed arm 10 disposed at a right angle to arm 9. AIn assembling the device, spring 7 is first bent to provide the arm 9 which is inserted through the diametrically extending bore 9a of rod 6, this borel communicating at one end with the axial groove 9b formed in the peripheral face of rod 6 and, at the other end, with the short groove 10a formed in the opposite face of the rod, After the arm 9 of spring 7 has'been inserted through the diametrical bore 9a, and the spring 7 is seated within the groove 9b, the portion of this arm which projects beyond the rod is then turned outwardly at a right angle so as to lit snugly within groove 10L Vthus producing the arm 10, as shown. The

Y ceive the set yscrew 12. having theintegrally inwardly extending pin 13. This pin 13 projects into the diametrical bore 14 adjacent the inner end of rod 6. This bore is positioned in the plane of bore 9a, and the pin 13 which extends into the same also projects through slot 8. By this means, l insure that rod- 6 will be at all times maintained in proper position in bore 4 for bringing spring 7 into register with slot 8 when the rod is moved into its innermost position. rfhe movement of rod 6 from one extreme position to the other may be readily accomplished by means of the collar 11. When the rod 6 is moved into its extreme outward position the spring 7 will be depressed and forced into the groove 9b of the rod so as to be contained entirely within the outline of the shank of the pin, as in Fig. 1 of the drawings. When the securing spring is in this position, the shank 2 of the pin maybe readily inserted through the crownof a hat in the ordinary manner. After the pin has been inserted into the hat crown, the collar 11 may be moved toward the head l so as to bring the spring 7 into register with slot -8 thus causing the spring to project through the slot and engage the inner face of the hat crown thus eeetually locking the pin Aagainst accidental Withdrawal, as in'Fi-g. 8 of the drawings, 'in which figure the locking spring 7 engages inside of the hat crown B. This movement of the collar 11 toward the head1 ofthe pin may be accomplished manually, or it may be effected by the simple expedient of pushing thel shank of the pin through the crown, the engagement of. the

collar with the hat crown serving to secure the collar againstmovement while the shank Q'is moved vforward relative to the collar thus bringing the spring 7 into register with slot 8 as in Fig. 8 of the drawings. When it is desired to withdraw the pin, the

collar 11 may be held against movement, the

head 1 and shank 2 carried thereby being drawn outward thus depressing the spring 7 so as to force the same into the groove 9a of rod6, afterV which the pin may be easily removed in the same manner as a hat pin of standard construction.

In the modified form shown in Figs. 6 and 7 of the drawings, the shank 2 is shortened 'and a tubular member 16 is interposed between the yshank and head 1. This tubular member is interiorly threaded at its inner end to receive the threaded stud 5 of the head, and is also interiorly threaded at its outer lend to receive a similar stud 17 carried by shank 2. This tubular member 16, when in position, forms practically an integralportion of thevpin, and replaces the portion of the pin containing the axial bore l1 in the form shown in Figs. 1 and 2 of the drawings. This tubular member 16 contains (miniemj o! this patent mayv be obtained for the rod. 6 and the locking spring carried thereby, and is operated Yby means ofthe collar 11 in the same manner as in the formV originally described.
